Question

For a body moving with constant momentum,the parameter which remains constant is-what?​

Answer 1

Explanation:

If the body is moving with constant momentum, its velocity will be constant since mass will be constant anyway. Alternatively, we know that force on a body is equal to rate of change of momentum. If momentum is constant, there will be no force on the body and therefore no acceleration.

Answer 2

Answer:

For a body moving with constant momentum, the parameter which remains constant is Velocity

Explanation:

Momentum is equal to m × v where m is mass and v is velocity. If the body is moving with constant momentum, its velocity will be constant since mass will be constant anyway.

Alternatively, we know that force on a body is equal to rate of change of momentum. If momentum is constant, there will be no force on the body and therefore no acceleration. It'll move with constant velocity.
